Class name: SURNAME_MATRIX Data fields: two(2) q xr arrays where: q = no. of characters of your first name. If q <= 5 then q = q * 2. r= no. characters of your surname. if r<= 5 then r=r*2. Methods: Constructor: initialize two(2) arrays. Value of each element = no. of characters of your fullname * 2.5. fillA1() - populate 2d-Array1 with random numbers. (200 max). seed - default fillA2() - populate 2d-Array2 with random numbers. (5000 max). seed - default addSubA1A2(int flag) - add or subtract the two matrices and display the resultant matrix (size is q xralso). (note: invoke first fillA1() and fillA2()) if flag is nonzero add matrices else subtract matrices. e.g. addSubA1A2(3) <-- add arrays, addSubA1A2(0) <-- subtract arrays toString() - displays the current date once and your fullname k times where kis a random number < 8.
